To all whom it may concern:

Be it known that we, Joint IRVING and ihLBERT JAMns RIsoN, both-citizens of the Dominion of NewZealand and. subjects of the King ofGreat Britaimand both rejsiding at 3 Anson Street, Vianganui, in the Provincial District. of Wellington, New

Zealand, have invented anlmproved Stamp and Method of Making Same,.ofwhich the following is a specification. v

This invention" relates to that class of stamps whereby letters, numerals or designs are reproduced by j means of perforations made in the 'material or substance to be stamped or marked, andprovidesa stamp which is of simpleconstruction and by which a signature, letters, numerals or designs can be accurately, readily and cheaply reproduced, in the form of perforations.

According to the invention the signature or design which is desired to be reproduced,

is written or drawn upon a sheet of paper which is then spread and secured upon a sheet of asbestos. The asbestos is placed upon a sheet of glass-or other hardsubstance having a flat surface, and the pins are stuck upright and close together through the signature or design, and'through the asbestos sheet until the points come into ,con 3 tact with the glass or other hard substance.

By this means the points of the pins are kept level with each other. The upper portions of the pins which project above the asbestos are then secured together and a "suitable fence or mould is placed around the edge of the asbestos. Solder, white metal, printers type metal or the like isthen run into the mould so formed and when set forms a solid backing in which the secured together ends of the pins are embedded.

The mould or fence and the asbestos are then removed leaving the pins projecting from the block of metal in the true conformation of the signature or design as first produced on the sheet of paper.

Theblock is then mountedon stock or handle. I

The invention will'be further described with the aid of the accompanying'drawing in which V Figure 1 shows in perspective a piece of paper, bearing a signature, secured on asbestos and pins inserted in the signature and asbestos to make contact with a'sheet. of glass beneath the asbestos. a

WELLINGTON, [New Figure .Zgis longitudinalsectional elevaef pins secured r is an end elevation A sheet. of asbestos Lof suitable size is;

paper 3 having'written or dreplacedupon a'slightly larger sheet of glass; '2 or other hard flat material. :Asheetyof j thereongi thesignature or design alwliichlit' is desired to reproduce is laid on topiof the asbestos sheet 1 and secured thereto by pins;;5 "or other suitable fastening means 7 PinsG are inserted upright and close to-Qv gether through the signature or designer I on the paper 3 and through the asbestos sheet 1 until the points of saidpins. 6 come into contact with the glass 2. r

' Pins are placed in this manner over the is whole of the signature or design 4.

The upper ends of the pins 6 which project above the asbestos sheet .1 are then secured together, preferably by tinning m1 soldering as shown at 7 in Figures 2 and'3. 1 'A mould or fence 8 (F gure 3) is now placed around the asbestos sheet 1 as it rests on the glass 2.

Solder, white metal, printers type metal or the like is then melted and poured into the space enclosed by mould or fence 8, said molten metal surrounding'thesecured together upper ends of the pins 6 and when set forms a solid block 9. from which the pins 6 rigidly project."

The fence or'mould 8, asbestos sheet 1 and glass 2 are now removed leaving the lower ends of the pins 6 projecting downwards from the solid metal backing ,9, in true'con formationof the signature or design 45.-

The metal block 9 is then mounted 'ona suitable handle or grip 10. l

If desired the metal block9 may be'pre j pared in a form suitable for use in a print ing machine or theilike, in which case the handle 10 can be dispensed with.

The inking of the pins 6 is effected by means of a pad of cork, this material allowing the pins 6 to enter freely and to be inked above their tips, thereby preventingrunning of the ink when using the stamp on soft fabrics or the like. i 1 i By using sp ns with blunt'ends, or with lower ends having a diameter equal to their stems, the stamp may be used for printing or stamping without perforating the material to which the stamp is applied.

What we do claim and desire to obtain by Letters Patent of the United States of America is 1. A method of producing a device of the kind described, comprising inserting pins in an inipcr'forate material to conform to the configuration of a design, securing a backing on the pins, and removing the material in which the pins were inserted.

2. A method of producing a device of the kind described comprising inserting pins in paper and a. soft material on which the latter is secured so as to conform to the configuration ot a design on the paper, the pin points being kept level with each other securing a backing on the outer ends of the pins, and removing the paper and material in which the pins were inserted.

3. A method of producing a device of the kind described comprising inserting pins in paper and a. soft material on which the latter is secured so as to conform to the con figuration of a. design on the paper and so that the pin points are kept level with each other securing together the outer ends of the pins; casting a backing on said outer ends, and removing the material in which the pins were inserted.

4;. A method according to claim 3 the soft material, being heat resisting.

5. A method of producing adevice of the kind described consisting in securing a paper with a design thereon on soft heat resisting material; placing'the latter on a hard flat surface; inserting pins in the paper and the soft heat resisting material so that the pin points make contact with said hard flat'surface; soldering the other ends of the pins together; moulding a backing on the secured together ends of said pins and removing the material in 'which the latter were inserted. v

In testimony whereof we have signed our namesto this specification in the presence of two witnesses.
